Extraction of Preisach model parameters for fluorite-structure ferroelectrics and antiferroelectrics

Abstract Flourite-structure ferroelectrics (FEs) and antiferroelectrics (AFEs) such as HfO2 and its variants have gained copious attention from the semiconductor community, because they enable complementary metal-oxide-semiconductor (CMOS)-compatible platforms for high-density, high-performance non-...
